Neem Extract Fights Zoo Parasites Effectively
4 Jul
Summary
- Neem seed kernel extract reduced ectoparasites by 69.33% in zoo animals.
- Flies were the most common parasite, making up 93.99% of infestations.
- Asian elephants showed the highest treatment response at 81.76% efficacy.

A pilot study conducted in 2025 at Rajiv Gandhi Zoological Park and Wildlife Research Centre explored the efficacy of neem seed kernel extract (NSKE) in controlling ectoparasites among captive wild animals. Researchers found that a 5% NSKE solution reduced these infestations by an impressive 69.33%.
The study, involving species like black buck, spotted deer, leopard, tiger, Asian elephant, and sloth bear, utilized non-invasive methods for parasite assessment. Over 19 days, parasite numbers dropped from 662 to 203 after a nine-day treatment period involving cleaning and spraying with NSKE.
Flies constituted the vast majority of parasites, with neem effectively reducing them by 69.29%. Lice and fleas were also significantly impacted, with fleas being completely eliminated. Asian elephants exhibited the highest treatment efficacy at 81.76%, while black bucks had the lowest initial parasite burden.
This research highlights neem-based formulations as a promising, biodegradable, and environmentally friendly alternative to synthetic insecticides, which often raise concerns about chemical residues and resistance. While the findings are encouraging, lead researcher Satyamurti Kendre noted the need for larger, long-term studies before wider adoption in zoo management.
